Writing a Fundraising Memo Instead of a Deck

Slides are good at showing. A memo is good at explaining. If your startup has a story that needs more than ten bullet points to make sense, a well-written fundraising memo can do what a deck cannot: walk an investor through your thinking, one clear paragraph at a time, long after you have left the room.

Most founders reach for slides by default. That makes sense: slide templates are everywhere, and investors expect to see something visual. But a growing number of founders also prepare a written memo, and some lead with it. A memo forces you to connect the dots that bullet points let you skip, such as why this customer has this problem now, and why your team is the one to solve it.

This guide is not about building slides, which we cover elsewhere. It is about the written alternative: when it helps, what goes in it, how to write it so busy people actually read it, and how to share it without losing control of the process.

A quick note: this article is general information about fundraising, not legal, tax or investment advice. Securities rules apply to how you raise money, so talk to a startup lawyer before you share offering details widely.

Why a memo can beat a deck

A deck is built to accompany a talk. On its own, it often leaves gaps, because the founder was supposed to fill them in out loud. When a deck gets forwarded to a partner who was not in the meeting, those gaps become doubts. A memo travels better because the reasoning is written down.

Situations where a memo shines

• Complex or technical products. Deep tech, health, climate and infrastructure companies often need a few paragraphs to explain how the product works and why it is hard to copy.
• Unusual markets. If an investor will not immediately recognize your customer or buying process, a memo gives you room to describe it.
• Investors who read first. Some firms circulate written material before a partner meeting. Giving them a ready-made document saves your champion from writing one about you.
• Remote processes. When most conversations happen over video, a document people can read at their own pace fills the space between calls.
• Follow-on and insider rounds. Existing investors already know the basics. A memo that focuses on progress and the plan for the new money often serves them better than a refreshed deck.

What a memo will not fix

A memo is not a shortcut around weak traction or an unclear market. If anything, writing in full sentences exposes weak spots faster. That is a feature: you would rather find the gaps yourself in March than hear about them from investors in April.

The structure of a strong fundraising memo

Think about the questions an investor will be asked by their own partners. Your memo should answer those questions in a logical order, so the reader never has to hunt. Here is a structure that works for most early-stage companies.

1. Summary

One paragraph, at most 150 words. What you do, for whom, the key proof point, how much you are raising and what it will achieve. If a reader stops here, they should still be able to describe your company accurately to a colleague.

2. The problem and the customer

Describe a specific customer, their painful situation and what they do about it today. Use the words customers use. Quotes from real conversations, with permission and without names if needed, are far more persuasive than adjectives.

3. The solution and how it works

Explain what your product does and, if relevant, how it works under the hood. Focus on the moments where your approach is clearly better than the current workaround.

4. Why now

What has changed in technology, regulation, behavior or cost that makes this possible or urgent today? This section separates a good idea from a good idea at the right time.

5. Traction and evidence

Share your real numbers: revenue, usage, retention, pilots, waitlists or letters of intent. Define each metric clearly. If you are pre-revenue, describe the experiments you ran and what you learned.

6. Market and business model

Explain who pays, how much, how often and how you reach them. Build any market estimate from the bottom up, using customer counts and realistic prices, rather than quoting a large top-down figure.

7. Competition and your edge

Name the real alternatives, including spreadsheets, agencies and doing nothing. Then explain why customers choose you and what will keep that true as you grow.

8. Team

Why are you the people to build this? Focus on relevant experience and evidence of speed, not a list of logos.

9. The raise and the plan

State the amount, the instrument if decided, what the money funds and the milestones it should reach. Investors want to see how this round sets up the next one.

10. Risks and open questions

List the two to four biggest risks and how you plan to reduce each one. This section builds trust quickly, because it shows you see your business clearly.

How to write it, step by step

A good memo usually takes a few drafts. Give yourself a week or two rather than a weekend, and get honest readers involved early.

1. List the ten questions. Write down the toughest questions you have heard from investors, advisers and customers. Your memo must answer every one.
2. Write an ugly first draft. Get every section down without polishing. Aim for completeness, not elegance.
3. Add the evidence. Go section by section and attach a fact, number or quote to each claim. Delete claims you cannot support.
4. Cut by a third. Remove repetition, jargon and throat-clearing. Most first drafts are far longer than they need to be.
5. Write the summary last. Once the body is clear, the summary almost writes itself.
6. Test it on a cold reader. Ask someone who does not know your company to read it, then explain it back to you. Wherever they stumble, rewrite.
7. Get a legal check. Ask your lawyer to review anything about the terms of the raise, forward-looking statements and how you plan to share the document.

Writing habits that make memos readable

• Use short paragraphs and descriptive headings so readers can skim.
• Put the conclusion first in each section, then the supporting detail.
• Define every metric the first time you use it, for example what counts as an active customer.
• Use one simple chart or table where a picture helps, and no more than a few in total.
• Prefer "we signed 12 paying pilots" to "strong early traction."

AI writing tools such as ChatGPT, Claude, Gemini or Grammarly can help you tighten sentences or spot unclear passages. Use them as editors, not authors, and never paste confidential data into a tool without checking its privacy settings and current policies.

A fundraising memo template you can copy

Use this table to plan your memo before you write. Fill in the main point and the best evidence for each section. The rows below are made-up examples for a fictional company.

Add the remaining sections from the structure above as extra rows. When every row has a clear point and real evidence, you are ready to write.

Sharing your memo the smart way

How you share a memo matters almost as much as what is in it. A few simple habits protect you and keep your process organized.

Decide when to send it

Some founders send a short email with the summary and offer the full memo on request. Others send it after a first call as a follow-up. Sending it after a conversation usually works better, because the reader already has context and a reason to read.

Control the version

Share a PDF or a view-only link, put a date and version number in the footer and keep a simple log of who received which version. If you update numbers mid-raise, send a short update note rather than silently replacing the file.

Mind confidentiality and securities rules

Most investors will not sign a non-disclosure agreement at the first stage, so leave out trade secrets and anything you could not afford to see in a competitor's inbox. Rules on how you may talk publicly about a securities offering differ by country and exemption. In the US and UK alike, keep the memo private and ask your lawyer before posting any version online.

Use it in the meeting

If an investor has read the memo, skip the overview and go straight to questions. You can say, "You have read the memo, so where would you like to dig in?" That turns a pitch into a working session, which is often where conviction is built.

Frequently asked questions

The bottom line

A fundraising memo is a simple idea with a big payoff. It makes you explain your company in plain sentences, backs every claim with evidence and gives investors something they can read, share and return to. Even if you still pitch with slides, the memo becomes the clearest version of your story.

Block out a few mornings this spring, work through the template above and test your draft on someone who has never heard your pitch. If they can explain your company back to you, your memo is ready to go.
